THEODORE BUTLER, OF NEW YORK, N. Y., ASSIGNOR TO THE J. L. MOTT IRONXVORKS, OF SAME PLACE.

BATH WASTE AND OVERFLOW.

SPECIFICATION forming part of Letters Patent No. 346,579, dated August3, 1886.

(No model.)

To all whom it may concern.-

Be it known that I, THEODORE BUTLER, of the city and State of New York,have invented an Improvement in Bath \Vastes and Overflows,of which thefollowing is a specification.

Bath overflow-pipes have been removable from the end of the fixedwaste'pipe at the bottom of the bath, but the same is very liable toinjure the metal lining of the bath-tub by being carelessly laid down ordropped into such bath-tub.

My present improvement relates to the overflow-pipe and the tubularperforated standing waste-pipe for the same, the movable overflow-pipebeing provided with annular elastic buffers at the ends, by which injuryto the bath-tub is prevented if the said pipe is laid down carelessly orfalls within the bath-tub. One of these annular elastic buffers forms avalve when the overflow-pipe is upon the tubular perforated standingwaste, and when the overflow-pipe is lifted it can be supported by abayonet-lock, to allow the water to pass off through the perforations inthe standing waste.

In the drawings, Figure l is a vertical section of the waste andoverflow. Fig. 2 is a seetional plan of the same, and Fig. 3 is anelevation.

The bottom a of the bath-tub is provided with a fixed waste-pipe, Z), ofany usual character. Preferably the said pipe is connected to the lowerend of the coupling 0, and at the upper end of the coupling is thevalve-seat (1, around which the sheet-metal lining of the bath-tub issoldered; or, in cases where this improvement is applied to a porcelainor castiron bathtub, the seat is received into a recess in the bottom ofthe tub, the nut a being used to clamp the parts in place.

Vithin and secured to the waste-pipe, and rising above it, is thestanding waste-pipe], that is of sheet-metal and perforated withnumerous holes, through which the water can escape freely. The movableoverflow-pipe h is of a size to pass freely over the stand-pipe f, andit is of a length that allows the water to flow over the top when themaximum height of water has been attained in the bath-tub. At the lowerend of this overflow-pipe 71 is a valve, 2', resting upon the seat (I,and forming This valve is preferably a water-tight joint.

a ring of india-rubber, that is sprung into an annular groove around thelower end of the stand-pipe. This overllow-pipe can be raised up toallow the water to escape through the perforations of the stand-pipe,and for the purpose of sustaining the overflow-pipe any suitable meansmay be made use of. I have shown a stud, 0, projecting inwardly from theoverflow-pipe and passing into a slot in the stand-pipef. This slot ismade with horizontal branch slots similar to bayonetlock slots, so thatthe overflow-pipe can be lifted, and then sustained by turning the pipein either direction to bring the stud into one of the horizontal branchslots, or the overflow-pipe can be lifted entirely off the stand-pipe.

To protect the bath from injury if the overflow-pipe is allowed to drop,I place a second elastic ring, Z, around the same at or near the upperend, and projecting sufficiently to form an annular elastic buffer. Thelower ring, 'i, also forms an annular elastic buffer, and it is shown asalso forming the valve. If both ends of the overfiow-pipe are madealike, the same may be placed over the stand-pipe f, with either enddownwardly.

I claim as my invention- 1.. The combination, with the bath-tub and theperforated standing waste-pipe rising above the bottom thereof, of aremovable overflow-pipe passing over the standing waste pipe, and havinga rubber ring around the lower end resting upon a seat around thewaste-pipe and forming a valve to the overflow-pipe, substantially asset forth.

2. The combination, with the stationary tubular perforated standingwaste-pipef, and a seat around the exterior surface of the same, of aremovable overflow pipe, an annular elastic valve around the same, and astud within said overflow-pipe and passing into a bayonet-slot in thestanding waste-pipe for sustaining the overflow-pipe when raised,and forallowing said overflow-pipe to be removed, substantially as set forth.

Signed by me this 12th day of April, A. D. 1886.

THEODORE BUTLER.
